Abstract: Sills are strongly loaded in particular by the leaf weight in large-leaf sliding doors. For this reason, it is usual to produce highly-loaded sills consisting of a tubular profile. Since the latter are relatively expensive, the invention aims to provide a sill which is relatively inexpensive to produce, but is nonetheless completely adapted to the loading which occurs. The latter is therefore designed as an essentially approximately U-shaped profile open to the bottom which is preferably stiffened at its lower end in at least one region, but preferably over its entire length, by means of a continuous connecting element (2). Advantageously, these U-shaped sills and the connecting element are connected together in a snap-in or catching manner. Moreover, the running rail (3) is advantageously moulded onto the U-shaped profile. The connecting element can be provided with a socket (30), open to the bottom, for a holding element, in particular for at least one wall anchor or the like. Advantageously, both the sill and the connecting element are produced as extruded profiles. <IMAGE>

Abstract: The invention relates to a winding suitable especially for high-tension windings for dry-type transformers having a multiplicity of turns (4) arranged radially above one another in a plurality of layers. According to the invention, arranged alternately on an inner supporting cylinder (2) of dielectric material there are in each case a blowhole-free layer (3) of a paste of dielectric material, which is still viscous during the winding process, and in each case a layer of the winding consisting of turns (4). In this arrangement, the individual turns (4) are pressed into the layer (3), located in each case radially beneath them, by an appropriate setting of the winding train and the winding is closed to the exterior by a topmost layer (6) of the pasty dielectric material. The viscous paste representing the layers (3) hardens after completion of the winding process. The advantageousness of this winding arrangement consists in that, on the one hand, it is as compact as a winding cast in synthetic resin and, on the other hand, it does not require the production complexity needed for the casting of windings. Winding arrangements according to the invention can be produced in virtually any dimension, in one and the same device. <IMAGE>

Abstract: A multi-layer information recording medium (11) for storing large amounts of information in a prescribed pattern of microscopic pits (15), formed by focusing onto the medium a beam of radiation having a prescribed wavelength and having an intensity modulated by the information to be recorded. The record medium (11) includes a substrate (29) having a light-reflective surface (31) on its upper side, a light-absorptive dielectric layer (33) overlaying the substrate and having a thickness approximately equal to an odd integral multiple of one fourth the wavelength of the beam of radiation in the dielectric material, and a thin metallic layer (35) overlaying the dielectric layer and having a light-reflective surface (37) on its lower side. During recording of the information, a substantial proportion of the intensity-modulated beam of radiation is transmitted through the metallic layer (35) to the dielectric layer (33) where it is confined, due to multiple internal reflections by the light-reflective surfaces (31,37) of the substrate and the metallic layer, until it is finally absorbed by the dielectric material. This causes an evaporation of the dielectric material (33) whenever the intensity of the beam exceeds a predetermined threshold, such evaporation carrying away the overlaying portions of the metallic layer (35) and creating the prescribed pattern of microscopic information-bearing pits (15).

Abstract: The output stage of a quasi-linear amplifier employs a p-channel and an n-channel FET (Ω1) with (Ω2) with their sources connected to relatively positive (B+) and relatively negative (B-) operating voltage rails to drive a load (LM) from their drain-to-drain connection, so that despite their being enhancement types full rail-to-rail output voltage capability (B+, B-) can be obtained without need for bootstrapping. Input signal voltage and direct-coupled feedback voltage are applied to the gate-to-gate connection of p-channel and n-channel sourcefollowers (Ω3) (Ω4) with their respective sources di- rectcoupled to the gate of the p-channel FET (Ω1) in the output stage and to the gate of the n-channel FET (S22) in the output stage, respectively, and with their respective drains connected to the relatively negative operating voltage rail (B-) and to the relatively positive operating voltage rail (B+) respectively, in a representative driver stage (Ω3, Ω4).
